We've all been there.

We've all seen it (at least once).

Perhaps even committed the "easy" crime.

আপনি know what I'm talking about.

"His cheeks were red with embarrassment."

"Anna checked the balance sheets again, coming to a conclusion the the financials were a deep crimson."

"I stared into his blue eyes as deep as the ocean."

Colors, like anything else, are powerful descriptive pieces. When used as a comparison অথবা a contrast, the reader is painted a picture of the person/object's look and the setting as a whole. It should make the scene come together in a seamless flow.

For example, the "red with embarrassment" idiom has... wore out its welcome if আপনি will. Many of us have seen this written and do আপনি ever wonder what else আপনি could describe embarrassment with?

Try this sentence.

"Our teacher announced Jake Foreman as the winner of the কবিতা contest. I had to nearly shove him out of the chair to get up to receive his award, standing up on shaky limbs. After he reached the teacher's ডেস্ক he grinned like crazy, cheeks brighter than the স্ট্রবেরি pendant he wore."

We see here that the red cheeks for embarrassment is a well known symbolism, but not one tied down to a specific idiom অথবা phrasing.

Also with colors, be careful not to mix too many contrasts as it may take away from the impact the color is describing.

From the blog WritersHelpingWriters:

"Once Wendy had loaded up at the buffet she sashayed to our table, smiling like she actually thought she belonged. She’d chosen a short ebony dress as her outfit this evening, which made her bloated white legs as appealing as soiled hospital linen."

What’s wrong with this example?

The emphasis is আরো on how the black স্কার্ট makes her legs look, rather than describe the স্কার্ট itself. If the black object is important, don’t let other things overrun the description.

Here's a stronger way to describe the skirt:

"Once Wendy had loaded up at the buffet she sashayed to our table, smiling like she actually thought she belonged. As she stood there balancing a heaped plate, I took a closer look at the ridiculous ebony dress encasing her chubby form. What was she thinking–a shiny number like that should make the wearer look sleek, not a dung beetle clinging to its precious meal."

Why is this example better?

It provides a simile that gives an apt image and also really says something about the nastiness of the person making the comparison.

Of course that's not to say that every single thing needs to have a specific detail on its looks, but it does invoke a stronger relation to the object and/or person one is trying to convey.
